GAS ORSOLIDFUEL FURNACE.

SPEGIFIGATION forming part of Letters Patent No. 752,461, dated February16, 1904.

Application filed August 13, 1903- To all whom it may concern.

Be it known that I, RUDoLrHA. MAY, acitizen of the United States,residing at Akron, in the county of Summit and State of Ohio, haveinvented a certain new and useful Improvement in Gas or Solid FuelFurnaces, of which the following is a complete specification.

My invention has relation to improvements in stoves, furnaces, and othercombustion devices for the successful burning of either solid Theobjects of my invention are to provide a stove, furnace, or othercombustion device which is readily applicable for use in thosecommunities where natural gas is a common fuel and one in which a solidfuel may be used or substituted upon a failure for any cause of thefluid fuel.

Another object of my invention is to provide devices for the ready andsuccessful handling and controlling of the fluid fuel, whereby the flamethereof may be thrown against the surface of the fire-pot orcombustionchamber with a view to communicating more heat thereto than ifthe flame was thrown into the center and to secure greater radiation ofheat from the fire-pot or combustion-chamber to the external air in thecase of a stove and in the case of a furnace to the air inclosed by thecasing.

A further object is to provide means whereby the dust incident to thecombustion of a solid fuel may be prevented from clogging the burnerused for the fluid fuel and at the same time to provide such cover forthe fluidfuel burner that it will in no wise impede the use of theburner for fluid fuel.

To the accomplishment of the aforesaid objects,my invention consists inthe peculiar and novel construction, arrangement, and combination ofparts hereinafter described, reference being had to the accompanyingdrawings, forming a part of this specification.

In the accompanying drawings, in which similar reference-numeralsindicate like parts in the different figures, Figure 1 is a section of afurnace which is here used to illustratethe application of my inventionimmediately serial No. 169,409. (No model.)

casing is the fire-pot 2, provided at the bottom with a grate 3, uponwhich is burned solid fuel. The construction of the furnace so fardescribed may be of any description wherein a solid fuel may be burned.Passing through the sides of the casing 1 and the firepot 2 are inletsor pipes 4, provided with gaskets or washers 5 where they enter thefire-pot, with a view to preventing the products of combustion in thefire-pot or combustion-chamber from entering the air-space situatedbetween the fire-pot and the casing 1. These inlet-pipes 4 are providedwith mixers 6 and ordinary valves or cooks for the control of the supplyof fluid fuel, but which are not deemed necessary to here describe orshow, as they may be of any ordinary construction.

Attached to the inner end of the inlet-pipes 4: are burners 7, thegeneral outline of which is substantially similar with the inner side ofthe fire-pot or combustion-chambers and are adapted to lie against theinner face thereof and conform thereto. These burners consist of apartially-cylindrical body having a slanting upper face 8, the slant ofwhich is toward the inlet-pipes 4. In substantially the center of thisinclined upper face is an opening 9, from which the fluid fuel flows.

The object of inclining this upper face of the burners 7 is to throw theflame of the fluid fuel against the inner side of the fire-pot orcombustion-chamber, as indicated in Fig. 2 by arrows.

Whenever it is desired to burn solid fuel in the furnace or stove, it isnecessary to cover the outlet 9 with a cover of some description,

and I preferably hinge on the extreme ends.

of the burners 7 a cover 10, which is arranged when swung in onedirection to completely cover the entire upper face of the burner, aswell as the outlet 9, to prevent the deposit of ashes and dust in thefluid-burner 7.

space within'the fire-pot is free at the time that the fluid-fuel burneris in operation the swinging of the hinged lids 10 into the main body ofthe fire-pot to uncover the outlets in the burners 7 in no wiseinterferes with the normal operation of the furnace or stove.

What I claim, and desire to secure by Letters Patent, is

In a stove, furnace or other combustion device arranged to burn a solidor fluid fuel the combination of a burner arranged to lie along theinner face of a fire-pot or combustionchamber provided with an outletfor a fluid fuel pointing substantially backward arranged to throw theflame of said fluid fuel against the inner face of said fire-pot orcombustionchamber and a cover to protect the outlet of said fluid fuelwhen not in use.

In testimony that I claim the above I hereunto set my hand in thepresence of two sub scribing witnesses.
